javascript/jquery search in a subarray?

Question

There is a string that is being formulated something like this Item:ShortName:Tax and if more items are added, it is appended to string like Item:ShortName:Tax_Item2:ShortName2:Tax2, adding one more, Item:ShortName:Tax_Item2:ShortName2:Tax2_Item3:ShortName3:Tax3 and so on. What I want to know is that, I have to check for if a item is present in the list, say, shirt, or jeans. It would be the first in array when separated by colon.

I used this.

var list = "Item:ShortName:Tax_Item2:ShortName2:Tax2_Item3:ShortName3:Tax3_Item4:ShortName4:Tax4";

$(document).ready(function () {
    var arg = 'Item2';
    findItem(arg);
    fucntion findItem(argument) {
        $.each(list.split('_'), function () {
            if (this.split(':')[0] == arg) {
                alert('Item found!');
            }
        };
        };

But the alert doesn't appear, though Item2 is in the list.
In case its not clear, this list split by _ contains a array (as you can see) and each of that array separated by : contains Itemname, ItemShortName, TaxOnItem, now in all those small array, I have to check for first array that contains the ItemName to see if a particular item exists or not! How can I do this?

You do realise you got an error in your code, fucntion findItem(argument) { } think you mean "function".

You are missing some { and ( as well as a typo. The console log tells you all this!

$(document).ready(function () {

    var list = "Item:ShortName:Tax_Item2:ShortName2:Tax2_Item3:ShortName3:Tax3_Item4:ShortName4:Tax4";
    var arg = 'Item2';
    findItem(arg);

    function findItem(argument) {
        $.each(list.split('_'), function () {
            if (this.split(':')[0] == arg) {
                alert('Item found!');
            }
        });
}

});

Here: I slightly ~~reformatted~~ restructured your code. Try this:

var list = "Item:ShortName:Tax_Item2:ShortName2:Tax2_Item3:ShortName3:Tax3_Item4:ShortName4:Tax4";

function findItem(argument) {
    list.split("_").forEach(function(subList){
        if(subList.split(":")[0] == argument) { 
             alert("Item found!");
         }
    });
};

$(document).ready(function () {
    findItem("Item2");
};
